They're the same industry. Impregnate cows to keep them producing milk, steal the babies away and either raise them to get impregnated or send them to be slaughtered for veal. You're either lying or clueless and I don't really care to find out which it is anymore, I've lost interest. Have fun.
You realise that veal is often just the calves taken from dairy cows, right? If you drink milk you are already supporting veal. They're killed anyway, it's just the difference between them being discarded or being sold.
